Hydraulic Swing Beam shearing machine control circuit failure

Hydraulic Swing Beam shearing machine control circuit failure

Hydraulic Swing Beam shearing machine is an important equipment in the forging and pressing industry, and whether the expected shearing action can be achieved is a prerequisite to ensure accuracy. In the past, the conventional design mainly relied on experience and analogy with the same type of machine, the design of a large iterative, long cycle, poor reliability. The machine not only has the function of ordinary shearing machine, increased the side knife, and can meet the longer plate trimming shear, in the rolling steel, boilers, shipbuilding and other industries have a broader application prospects.

Hydraulic Swing Beam shearing machine due to the manufacture of most of the mounting surface of the blade frame using a simplified process, the blade mounting surface from the space spiral surface simplified into a plane, resulting in the shear gap and shear angle changes in the shearing process. Shear gap changes will make the shear process shear force size changes, shear quality decline; and shear angle changes can intensify the blade and plate wear and even extrusion, and then increase the shear force. Therefore, the use of Noshari formula calculated shear force value only as a reference value for adjusting the size of the shear force, the actual shear force required in the shearing process is the size of the production site through continuous adjustment supplemented by shear plate test.

Therefore, in dealing with the cartridge valve structure of the hydraulic system failure, you need to clearly understand the role of each component in the system, if necessary, can be equivalent to simplify the ordinary hydraulic valve, in order to more intuitive analysis of the role of each cartridge circuit in the entire hydraulic system, so as to quickly and accurately identify the system failure, and timely elimination of it. is mainly composed of frame, knife frame, cylinder, pressure foot, alignment device, gap adjustment device, hydraulic system and electrical system and other components. Shearing machine in the shearing of the plate material, the hydraulic system pressure setting value and edge clearance value directly affect the quality of the cut.

Hydraulic system is composed of cartridge structure of integrated block valve, motor, oil pump and its pipeline, etc. Hydraulic directional control valve, pressure control valve, flow control valve has been unable to meet the parameters of this system, so the use of cartridge valve structure hydraulic system. Cartridge valve hydraulic system is a number of cartridge components for different combinations, and with the corresponding pilot control level composed of directional control, pressure control, flow control and composite control valves, this structure control valve has a large flow capacity, control automation and other significant advantages, so it has become the leading control products in the field of high pressure and high flow.
